Role of expertise and action in motion extrapolation from real road scenes

Abstract : The tendency of participants to ``remember'' the stopping point of an event as being farther along in the direction of motion has been a topic of study for about 30 years. The purpose of the present experiment was to test the influence of two factors on motion extrapolation: (1) The involvement of participants in the action, and (2) their expertise in the domain of automobile driving. Participants viewed real driving scenes from the driver's point of view. They were divided into four groups depending upon their involvement in the action (more or less active) and their driving experience (inexperienced or experienced). In order to get half of the participants involved in the driving situation, they had to use a steering wheel to follow the contour of the road. The results showed that both of these factors increased motion extrapolation. The discussion deals with how the interrelationships between real road scenes, expertise, and action-related knowledge affect motion extrapolation.
